Sometimes the waves spin seaweed and bits of rope into designer yarn of the sea.
But more often what washes up is not so picturesque. Spring Bay is a pretty clean beach, but every morning I manage to gather a handful of plastic trash that the tide had brought in. Included were the expected pop bottles and candy wrappers, but also a couple of spent shotgun shells and a used insulin syringe. There were a lot of tampon applicators, (shame, sisters!), a high heel platform shoe, and numerous zip lock bags.
Guess what topped the trash list? Plastic water bottle caps. Another reason to stick with tap water.
(I eventually filled a big trash bag with the plastic, and took it back with me to the mainland recycling centre.)
